[0002] Toolboxes are often provided in mechanical engineering equipment. Taking excavators as an example, their toolboxes are used to store special tools for excavator operation and maintenance, reducing the time spent going to the work area to retrieve or search for tools during construction.

[0003] In the prior art, the excavator toolbox includes a cover and a body. The cover is mounted on the body via a guide rail and a bracket. The guide rail has a snap-fit ​​groove. One end of the bracket is connected to the cover, and the other end is slidably mounted on the guide rail. When the cover is opened, the end of the bracket slides from its initial position along the guide rail until it snaps into the snap-fit ​​groove to achieve bracket positioning. When the cover is closed, the end of the bracket needs to be manually removed from the snap-fit ​​groove and placed into the guide rail first, and then the bracket slides along the guide rail to its initial position.

[0004] However, when closing the lid, the end of the bracket needs to be manually removed from the snap-fit ​​slot and placed into the guide rail, which is inconvenient. Utility Model Content

[0005] This application provides a toolbox and excavator to solve the problem that when closing the toolbox cover, it is inconvenient to manually remove the end of the bracket from the snap-fit ​​slot and place it into the guide rail.

[0014] In one possible implementation, the toolbox in this embodiment includes a reversing component comprising a fixed part, a rotating part, and a fixed shaft. The rotating part is sleeved on the fixed shaft and inserted into the fixed part. The fixed part is located on one side of the guide groove, and the rotating part is rotatably disposed in the guide groove around the fixed shaft.

[0015] In one possible implementation, the toolbox in this embodiment of the application further includes a guide member in the guide rail assembly. The support member includes a mounting part and a support part connected to the mounting part. The support part has a mounting groove. The guide member is disposed in the mounting groove, and a guide groove is formed between the guide member and the support part.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In the prior art, the excavator toolbox includes a cover and a body. The cover is mounted on the body via a guide rail and a bracket. The guide rail has a snap-fit ​​groove. One end of the bracket is connected to the cover, and the other end is slidably mounted on the guide rail. When the cover is opened, the end of the bracket slides from its initial position along the guide rail until it snaps into the snap-fit ​​groove to achieve bracket positioning. When the cover is closed, the end of the bracket needs to be manually removed from the snap-fit ​​groove and placed into the guide rail first, and then the bracket slides along the guide rail to its initial position.

[0045] However, closing the case requires manually removing the end of the bracket from the snap-fit ​​slot and placing it into the guide rail, which is inconvenient. Furthermore, when the case is open, the opening of the snap-fit ​​slot is perpendicular to the horizontal sliding direction, posing a risk of the bracket end coming loose during use.

[0046] In view of this, embodiments of this application provide a toolbox and an excavator, comprising: a box body; a box cover, the box cover being hinged to the box body, the box cover rotating relative to the box body to open and close the box body; a movable member, one end of the movable member being hinged to the box cover; a guide rail assembly, the guide rail assembly including a support member, the support member being disposed on the box body, the support member having an annular guide groove, the other end of the movable member being slidably disposed within the guide groove; the guide groove having a limiting part and a resetting part, the movable member being configured to move within the guide groove under the drive of the box cover to switch between an open box body and a closed box body state, the movable member being disposed within the limiting part when the box body is open, and being driven to disengage from the limiting part along the resetting part when the box body is closed. The annular guide groove separates the movement channels for opening and closing the box body; when switching from a closed box body state to an open box body state, the box cover is rotated, causing the movable member to move from its initial position along the guide groove to the limiting part, and being limited by the limiting part to maintain the open state. When switching from the open state to the closed state, continue rotating the lid to move the moving part away from the limit part along the reset part, then rotate the lid in the opposite direction to move the moving part back to the initial position. Automatic reset can be achieved with one hand, making the operation quite convenient.

[0047] The following is combined with Figures 1 to 8 The present application will be described in detail with reference to specific embodiments.

[0048] On one hand, this application provides a toolbox, including: a box body; a box cover, the box cover being hinged to the box body, the box cover being rotatable relative to the box body to open and close the box body; a movable member 100, one end of the movable member 100 being hinged to the box cover; a guide rail assembly 200, the guide rail assembly 200 including a support member 210, the support member 210 being disposed on the box body, the support member 210 having an annular guide groove 300, the other end of the movable member 100 being slidably disposed within the guide groove 300; the guide groove 300 having a limiting part 221 and a resetting part 222, the movable member 100 being configured to move within the guide groove 300 under the drive of the box cover to switch between an open box body and a closed box body state, the movable member 100 being disposed within the limiting part 221 when the box body is open, and being driven to disengage from the limiting part 221 along the resetting part 222 when the box body is closed.

[0049] Specifically, the support member 210 is plate-shaped, with an annular contour designed on it, and a guide groove 300 is formed by drilling. Alternatively, the guide groove 300 can be formed by directly drilling holes in the inner wall of the housing; this application embodiment does not limit the implementation method of the guide groove 300. For example, the guide groove 300 can also be an annular guide groove 300 formed by inner and side support plates with special contours, so that the moving member 100 can move.

[0050] It also includes a reversing member 230, which is used to realize the unidirectional movement of the moving member 100. The reversing member 230 is rotatably disposed within the guide groove 300. This application embodiment does not limit the structure of the reversing member 230. For example, the reversing member 230 is a guide plate, which is rotatably disposed within the guide groove 300. The moving member 100 is a support rod. The guide plate changes the moving direction of the support rod. When the lid is rotated to open the box, the guide plate is located behind the support rod, restricting the reverse sliding of the support rod and realizing unidirectional passage. When the lid is rotated to close the box, the guide plate is located in front of the support rod. The support rod pushes the guide plate to rotate, and the guide plate opens the moving channel of the guide groove 300. The support rod returns to its initial position. At this time, the guide plate is located behind the support rod, in the initial state of restricting the reverse sliding of the support rod. The reset part 222 is located on one side of the limiting part 221. The moving member 100 moves along the reset part 222 to disengage from the limiting part 221 to the guide groove 300, thereby driving the lid to close the box. The support member 210 is also provided with an arc-shaped recess that matches the reset part 222, such as Figure 5 As shown in E, an arcuate channel is formed between the arcuate recess and the reset portion 222 so that the moving member 100 can move along the reset portion 222.

[0051] Furthermore, the guide groove 300 includes a starting section 310, a first sliding section 320, a reset section 330, and a second sliding section 340 connected in sequence, wherein the second sliding section 340 is connected to the starting section 310, making the guide groove 300 annular in shape. The initial position of the moving member 100 is located at the starting section 310, and the reset part 222 is disposed on the reset section 330. During the process of switching the housing from the closed state to the open state, the moving member 100 moves from the initial position, passes through the starting section 310 and the first sliding section 320 in sequence, and enters the limiting part 221, keeping the housing in the open state. During the process of switching the housing from the open state to the closed state, the moving member 100 moves along the reset part 222, disengages from the limiting part 221, and enters the reset section 330 and the second sliding section 340 in sequence, returning to the initial position.

[0052] It should be noted that the reset part 222 can be an inclined protrusion located in the guide groove 300. The reset part 222 is higher than the limiting part 221. The opposite surface of the limiting part 221 is provided with a flange structure. By cooperating with the limiting part 221 through the flange structure, the moving part 100 can be prevented from directly entering the reset section 330. Of course, the limiting part 221 can also be cooperated with a torsion spring limiting device. The torsion spring limiting device can prevent the lid from directly entering the reset track when it is opened. For example, it can prevent the lid from switching from the open state to the closed state due to mechanical vibration.

[0053] The working principle of the toolbox in this embodiment is as follows: the toolbox lid, the movable part 100, the box body, and the annular guide groove 300 form an offset crank-slider mechanism. The guide groove 300 is set on the box body as a frame, the movable part 100 is a connecting rod, and the two ends of the movable part 100 form sliders. One end is hinged to the box lid to form a rotary joint, and the other end slides in the guide groove 300 to form a sliding joint. The box lid acts as a crank and is connected to the box body through a hinge to form a rotary joint.

[0054] In some embodiments, a door lock is also provided on the lid and the body of the toolbox. The guide groove 300 includes an actuation section 310, a first sliding section 320, a reset section 330, and a second sliding section 340 connected in sequence. The initial position of the moving member 100 is located at the actuation section 310, and the guide plate is disposed at the actuation section 310. The door lock is located on the lid and cooperates with the door lock plate on the body to realize the locking function when the toolbox is closed.

[0055] When the toolbox lid is closed, the movable component 100 is in the initial position. When the door lock is opened and the toolbox lid is gradually opened, the movable component 100 slides diagonally upward along the guide plate under the action of the lid and enters the first horizontal sliding section 320. As the opening angle of the lid increases, the movable component 100 is restricted by the flange, such as part A, and then engages in the limiting part 221, thereby opening the toolbox lid and maintaining its open state. When closing, the lid is lifted further upward, which will drive the movable component 100 to pass through the reset section 330 along the reset part 222, such as the groove opening in the guide groove 300, and enter the second sliding section 340. When the lid is closed to a certain angle until it is completely closed, the movable component 100 will push open the guide plate and enter the initial position. After the movable component 100 passes, the guide plate automatically resets. Thus, the toolbox lid completes the cycle of initial position - open state - initial position.

[0056] It should be noted that when the toolbox moving part 100 enters the limiting part 221 to achieve the limiting, the moving part 100 forms an obtuse angle with the horizontal guide rail, which is beneficial for limiting and preventing the moving part 100 from coming off when subjected to severe vibration.

[0057] In this embodiment of the toolbox, the moving channels for opening and closing the box are separated by an annular guide groove 300. When switching from the closed state to the open state, the lid is rotated, causing the moving part 100 to move from its initial position along the guide groove 300 to the limiting part 221, where it is stopped to maintain the open state. When switching from the open state to the closed state, the lid is rotated again, causing the moving part 100 to disengage from the limiting part 221 along the reset part 222. Then, the lid is rotated in the opposite direction, causing the moving part 100 to move back to its initial position. Automatic reset can be achieved with one hand, making operation convenient.

[0058] In one possible implementation, the toolbox in this embodiment includes a guide groove 300 comprising a starting section 310, a first sliding section 320, a reset section 330, and a second sliding section 340. The first sliding section 320 and the second sliding section 340 are disposed opposite to each other. A groove is provided between the first sliding section 320 and the reset section 330 to form a limiting part 221. The reset section 330 has an inclined end to form a reset part 222. The starting section 310, the first sliding section 320, the reset section 330, and the second sliding section 340 are sequentially connected to form a ring.

[0059] It should be noted that the first sliding segment 320 and the second sliding segment 340 are horizontally arranged, and a groove is provided between the first sliding segment 320 and the reset segment 330 to form a limiting part 221.

[0060] In one possible implementation, the toolbox in this embodiment of the application has an inclined end connected to a groove, with the top of the inclined end higher than the top of the groove. This allows the inclined end to provide a stop and limit function for the movable part 100 when the lid is kept open, so that the movable part 100 is securely located in the groove and prevents it from falling out of the groove.

[0061] In one possible implementation, in the toolbox of this application embodiment, the center line of the limiting part 221 is on the same straight line as the extension direction of the moving member 100 when it is disposed on the limiting part 221.

[0062] For example, the limiting part 221 is a groove, and the angle between the center line of the groove and the moving part 100 moving along the guide groove 300 to the limiting part 221 is an obtuse angle, which is beneficial for limiting and prevents the end of the moving part 100 from disengaging from the limiting part 221 to the first sliding section 320 when subjected to vibration, thus causing limiting failure.

[0063] In some embodiments, the top of the limiting portion 221 is flush with or below the bottom of the first sliding segment 320, thereby preventing the end of the moving member 100 from disengaging from the limiting portion 221 to the first sliding segment 320 when subjected to severe impact.

[0064] In one possible implementation, the toolbox in this embodiment of the application has a stop 211 on the support member 210. The stop 211 is connected to the guide groove 300. The stop 211 is disposed away from the reset member 222. The stop 211 is used to stop the moving member 100.

[0065] When the lid is switched from the closed state to the open state, one end of the moving member 100 moves from the stop part 211 along the guide groove 300 to the limiting part 221. When the lid is switched from the open state to the closed state, the moving member 100 moves along the reset part 222 to disengage from the limiting part 221 to the guide groove 300, and moves along the guide groove 300 to the stop part 211.

[0066] It is understandable that the stop part 211 is the initial position of the end of the moving part 100. When the lid is closed, the stop part 211 can limit the movement of the moving part 100 and prevent the moving part 100 from moving.

[0067] In one possible implementation, the toolbox guide rail assembly 200 in this embodiment of the application further includes a reversing member 230. The reversing member 230 is rotatably disposed at one end of the guide groove 300 away from the limiting part 221. The reversing member 230 is used to open or close the guide groove 300. The moving member 100 is used to drive the reversing member 230 to rotate so as to open the guide groove 300 and abut against the stop part 211.

[0068] In one possible implementation, the toolbox in this embodiment includes a reversing component 230 comprising a fixed part 231, a rotating part 232, and a fixed shaft 233. The rotating part 232 is sleeved on the fixed shaft 233 and inserted into the fixed part 231. The fixed part 231 is located on one side of the guide groove 300, and the rotating part 232 is rotatably disposed in the guide groove 300 around the fixed shaft 233.

[0069] The rotating part 232 is sleeved on the fixed shaft 233 and inserted on the fixed part 231. The fixed part 231 is located on one side of the guide member 220. The end of the guide member 220 has a rotating groove. The rotating part 232 is at least partially rotatable in the rotating groove around the fixed shaft 233.

[0070] In one possible implementation, the toolbox in this embodiment of the application further includes a guide member 220 in the guide rail assembly 200. The support member 210 includes a mounting part 212 and a support part 213 connected to the mounting part 212. The support part 213 has a mounting groove 214. The guide member 220 is disposed in the mounting groove 214. A guide groove 300 is formed between the guide member 220 and the support part 213. One end of the mounting part 212 is used to connect to the box body, and the other end is connected to the guide member 220.

[0071] Specifically, the mounting part 212 is an L-shaped plate, the support part 213 is an outer support plate, and the guide member 220 is an inner support plate. The outer support plate has a hollowed-out interior forming the outer contour of the guide groove, and its shape is designed according to the movement trajectory of the moving member 100. The inner support plate is also designed according to the movement trajectory of the moving member 100, and together with the outer support plate via the L-shaped plate, it forms the guide groove 300. Its limiting part 221 forms an obtuse angle with the horizontal guide groove 300, consistent with the extension direction of the moving member 100 after the lid is opened. The rotating part 232 is a guide plate, and the fixing part 231 is a mounting block. The mounting block is used to mount the guide plate and is welded to the inner support plate. The guide plate, as a moving member, is rotatably mounted on the mounting block, serving as a check valve and guide.

[0072] It is understandable that the outer and inner support plates are coplanar and are assembled using L-shaped plates.

[0073] In one possible implementation, the toolbox in this embodiment has a flange on the support portion 213 that matches the limiting portion 221, such as... Figure 5 As shown in A, the flange is used to guide the moving member 100 to move into the limiting part 221.

[0074] For example, the outer support plate is designed with a flange structure, which cooperates with the groove to achieve a limiting effect and prevent direct entry into the reset section 330. The support portion 213 is provided with an arc-shaped recess that matches the reset portion 222, such as... Figure 5As shown in E, the moving member 100 is disengaged from the limiting part 221 along the reset part 222, passes through the reset section 330, and enters the second sliding section 340. The arc-shaped recess is located on one side of the flange and is connected to the flange. It can be understood that the flange adapted to the limiting part 221 is used to guide the moving member 100 into the limiting part 221. The arc-shaped recess adapted to the reset part 222 forms an arc-shaped channel with the reset part 222, providing movement space for the moving member 100 to disengage from the limiting part 221, facilitating the moving member 100 to move along the reset part 222 into the reset section 330. On the other hand, this application provides an excavator, including a body and a toolbox in any of the above embodiments.

[0075] This application does not limit the structure of the excavator. For example, the excavator can be a tracked excavator, a wheeled excavator, a front shovel excavator, a backhoe excavator, a clamshell excavator, or a dragline excavator. The toolbox can be located on both sides of the machine body, near the engine compartment, or behind the cab; this application does not limit this location.

[0076] In this embodiment, the annular guide groove 300 separates the moving channels for opening and closing the housing, and the reset part 222 facilitates the automatic reset of the moving part 100 with one hand when closing the housing, making the operation more convenient.
